| Myomeres 10-12+14-16=24-26; body becomes covered with spinules, beginning along lateral midline of tail in yolk-sac or early preflexion stage, extending forward to pterotic by 3.6 mm, abdominal series added by 4.2 mm; numerous ridges form on cranium. Pigmentation: Preflexion-postflexion: spreading forward on dorsum to midbrain by 3.2 mm and to tip of snout by 3.6 mm; spreading laterally from dorsum beginning in middle of tail by 3.3 mm; stripe along lateral midline at postanal myomeres 1-10; body becoming completely pigmented by 3.6-4.2 mm, except none on last 2-3 myomeres or ventrally on posterior part of gut or on fin membranes. Transformation: completely pigmented except on pelvic and pectoral fins, second dorsal fin, anal fin, and caudal fin; darker dorsally; stripe along lateral midline of tail remains visible through about 10 mm. Sequence of fin development: caudal, pectorals, dorsal, anal, pelvics. | ||||
